My invention relates to improvements in combined, cooking and heating stoves'. It is particularlywell adapted for use-in connection with stoves which use oil or gas for fuel.- One'of the objectsof my'invention is to provide. a stove of the kind described, which is relatively simple and cheap, tov construct,

which isdurable and not liable'to get out of order, which is economical in fuel consump-. 10

tion, which inay bevused forflcooking or heating alone, or which may be used. simultane ously for both cooking and heating, which is easy tooperate and simple in operation, and which disch-argesthe gaseous products offcom bustion from the room containing the stove. A further object of my invention s the provision of a novel oven. s Still'a'nother object ofmy inventlon 1s the used for heating purposes in connection with the cooking portion of the stove, and which secures economical fuel consumption, when the stove is used elther for cookmg. or heat-' ins, o b h My invention also provides a novel'burner adapted for gas or. oil and for use in con nection with'rny 'improvedstove. The novel features of'myinventionare hereinafter fully described and claimed. 1 In the accompanying drawings whichil lustr ate -the preferred embodiment of 'my lit 1 Fig.1 is a front elevation of my improved sto Y I provision of a novel radiator adapted to'be i Fig, 2 isacentral vertical sectionalview 5 is .a horizontal v section, partly imitate-.1 1 1 designate 1 designatesthe stove body of the type usuallyemployed for cooking ranges, and having a combustion chamberQ, provided with the usual top openings13over which are adapted o. efd p se the usual ids or grids; y T i I The body of the stove, has above the combustionchamber 2 and spaced therefrom, an oven 5, into the bottom of which discharges a pipe 6, the lower endjof which communi cates with the combustion chamber 2, and in which i s a damper 7, 1 1 p In the oven'5 is a transverse perforate partition 'S, Fig. 2, which divides the'oven into an upper chamber 9 and a lower cham ber 1 0 The upper chamber 9. is a baking i chamber and has theusual front door 11.

the lower. chamber l0 extending from is a transverse baflle plate 12, the front edge of which is spaced from the front wall of the 10, and which is spaced from which'has it a damper 16 and which dis charges intoa main discharge pipe 17. v ."AuXilTiary'means for discharging vthe'gasf eons prod'uctsof "combustion, from the combusti'on chamber 2 are provided, andcomprisesfan auxiliary discharge pipe 18 into 1 which dischargesadOmbustion chamber dischargepipe 19 connected with the, rear; side of the combustion chamber and having in. it a'damperZO. .The up per end of the pipe .18 is connected leasethe vent, Fig.

to the pipe intermediately ofthe damper I side to side thereof and from the rear side I the different sections are centrally connected by horizontal longitudinal tubes 23.

In the drawlngs, four sections are shown, and the front tubes of the two upper sectlons are centrally connected by a vertical tube 24,

the two lower sections also being connected by a vertical tube connected to the front tubes 21 of said lower sections atthe centers of said'tubes. A vertical tube 26 centrally connects the two rear tubes 21ofthe two 7 intermediate sections.

The main discharge pipe 17 is centrally connected to thejrear tube 21 of the lowerniost. section, and the auxiliary pipe 18 is centrally connected to the rear tube 21 of the top'section.

The radiator rests on a base 27 the up per edges of the sides of which have arcuate recesses in which rest the end portions of the tubes 21 of the lowermost, section.

Vertical brace bars 28 are fastened to the front tubes of the four sections, and similar bars are similarly attached to the rear tubes 21' of the diflerent sections. 7

.Horizontal brace bars 29 are fastened to the sections 21 of the uppermost section, and. upon these bars rests the stove body 1.v

Any suitable gas or oil burners may be used. with the stove. ,To prevent the ac- 1 cinnulation in the pipes of soot, the burners used should burn gasor oil with a blue flame. 1 r

In the drawings I have shown three burners of my invention,-which are adapted to burn gas or oil with blue flames, and each of which comprises a channelbase 30, Figs.

3 and 1 provided with a fuel supply pipe31. T he three fuel supply pipes 31 are respectively connected toethree branches 32 of a horizontal fuel supply pipe 33, on the ends of which are respectively fitted removable caps 34. and 35. 'Foruse withgas, the cap 35-is removed and the pipe 33 is attached at that end to a gas supply pipe, not showna For use with oil, the pipe 33 hasavertical branch 36 having a shut off valve 37 and connected at its upper end with an oil tank 38 provided with the usual top closure 39.

In the branches 32 are respectively mounted three needle valves 40.

y In each channel base30, and fitted to the nner side of the outer wall of the channel 1s a vertical perforated tube 41; The

tubes 11 extend respectively through holes provided therefor in the bottom of the com.- bustion chamber 2. i

In each channel base ring 30 is also fitted to the outer side of the inner wall of the channel a vertical perforated tube 42 of the height of the adjacent tube 11 and having its upper end closed by a circular horizontal plate 43. v

Supported in and by the base ring 30 between the tubes 41 and 42 is a perforated ring 14, upon which is adapted to rest an asbestos wiclr-ringkto, when oil is being burned, but which may be removed, if gas is to be burned. The ring serves to diffuse the gas that is fed into the channel base 30, when gas is used. p

In the positions of the dampers 7, 16'and 20, shown in Fig. 2, the stove is adapted for both baking and heating simultaneous 1y. In such position of the dampers, the gaseous products of combustion will travel from the combustion chamber 2 through the p pefi into the chamber 10 of'the oven 5,

thence around and over the battle plate 12 and through the partition 811110 the chaniber 9, which is the baking chamber, thence through the pipes 15 and 18 into the center of the rear tube 21 of the top'radia'tor section. Thence the gas divides and passes from the ends of the'tube through the side tubes 22 into the next tube 21, thenceto the center of this tube and out through the adjacent central tube 23 to the tube12l next in front, thence to the ends of this tube and.

through the next side tubes 22 into the front tube 21 of the top section. The gas then travels to the center of this front tube to the front vertical tube 2 1, thence downwardly into the center of the front tube .21 of the next lower section. The gas then passes in a similar manner through the second sec:

tion to the rear tube 21 of such section,

thence downwardly through the centralvertical tube 26 into the third section vfrom the top, ,thence forwardly through this section by dividing and'uniting, as above described to the front tube of the third sec-- tion, thence downwardly jthrough'thefcentral tube 25 into the center of the front'tube 21 of the lowermost section, and thence through this section to and out of the central part of the rear tube 21 of the loWermost section into the main discharge pipe 17 by which the gas is discharged into the fine, not shown. r The air for combustion which enters a the front of the stove under the combustion chamber 2, passes through and is retarded by the perforated tubes 41 and 412,.thus mingling and being burned with the vapor from the ignited oil. The burntgaseous products are also retarded in their passage to the pipe 17 by the sinuous coursetaken through the oven, pipes 15, 18 and radiator tubes, so that by the time. that they reach the pipe 17, the heat has been mostly absorbed or radiated, thereby e-fi'ecting such heating and cooking as is desired with a minin'iun'i of fuel. I

If it is desired. not to bake in the oven 5, the damper 7 is closed, and the damper :20 is opened. If it is desired not to heat with the radiator, the damper 16 is opened, thus permitting the gaseous products to pass directly from the vcombustion chamber 2 through the pipesl9, 18and to the main discharge pipe 17. I

I do not limit my invention to the structure shown and described, as many modifica tions, within the scope of the appended:
